Ecosystem Ecology

In the 1930s, the last wolves disappeared from Yellowstone National Park. Without them, elk herds overran the plains. Bears starved, rabbit families shrunk and birds flew away to new homes. Then plants and trees started to die off, too—even the flow of rivers was affected. Could the park be saved...by the wolves it had lost? After years of planning, in 1995 a team of experts was ready to find out. They carefully relocated 14 wolves from the Canadian Rockies to Yellowstone. This is the story of their homecoming.

In Florida, there exists a very special ecosystem where sub-tropical and north-temperate vegetation meet—Bulow Hammock. Saved by conservationists, it is one of the last stands of forest on the East Coast. This hardwood grove in Florida's open marshes and pine wood is now a State Park where complex life thrives. In the tradition of Peter Matthiessen and Stephen Jay Gould, David Rains Wallace links natural history with the imagination for an intensive study of this unique and beautiful ecosystem.

Ziehen Sie Ihre Schwimmflossen an und setzen Ihre Sauerstoffmaske auf, tauchen Sie ins Meer und lassen Sie sich in einem ruhigen Tempo unter Wasser treiben. Verspielte Delfine machen klickende Geräusche, wenn sie vorbeischwimmen, und deine Maske erzeugt winzige, metallisch klingende Blasen, die zur Oberfläche aufsteigen. Vielleicht hören Sie sogar ein paar Walgesänge von den sanften Giganten des Ozeans.

Over the canyon, the sun scalds the air and bakes the desert mud to stone.

The diversity and abundance of life was immediately evident to all who came here”.

What do these top predators have to do with an aquatic grass at the opposite end of the food chain?
